Application filed July 7, 1925. Serial No. 41,981

The object of this invention is to devise 'a novel stove wherein novel means are provided for adjusting the locationofa fire so that the fire contact will be restricted'to heating the walls of one fire pot, or will heat to a desired degree at the same time the wal s of another fire'pot, said fire pots, if desir d, being water jacketed.

With the above and other objects in view which will hereinafter appear, my invention comprehends a novel stove wherein novel means are provided to adjust-a fire so that the fire contact of a fire with two independent surfaces to be heated maybe restricted to one surface or may eo-operate in a desired relation with two independent 7 or separate surfaces to be heated.

My invention further comprehends a novel hot water stove having two independent water heating systems, and novel means for adjusting the location of a fire to cause it to heat one or ing systems.

stove having a plurality of superimposed water jacketed fire pots, forming parts of independent hot water heating systems and having a source of heat for each fire pot, with means for relatively adjusting the sources of heat, and with means for simultaneously shaking the grates 0f the sources of heat.

It further comprehends other novel features of construction and advantage which will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in the accompanying drawings typical embodiment of it, which in practice, will give reliable and satisfactory results. i

It is, however, to be understood that this embodiment is 'typical only and that the various instrumentalities of which my invention consists can be variously arranged and organized, and that the invention is not, therefore, limited to the precise arrangement and or anization of these instrumentalities as here n set forth.

'1 designates a stove embodying my invene tlon, and which, for thepurpose of illustration, I have shown as a hot water stove.

The general construction ofthe stove may vary widely in practice but preferably iconforms tothat shown in my pending application Serial No. 732,623. f The stove as illustrated has a base 2 on which is mounted a base top or ash pit ring 3 which is flanged at its top to receivea preheater 4. This preheater 4 is in the form of a ring shaped casting havingajwater chamber 5 to which cool or coldwater is admitted by a conduit 6 leadingfrorn a boiler (not shown).

The preheateris recessed at its upperend to receive the cored or water jacketed .fire pot 7, the water chamber 8 of which is pref;- eraibly of greatest diameter intermediate its en 5.

The the pot 7 carries at its upper end a draft ring 9 having at its bottom an outwardly extending flange. The draft ring 9 is provided with a desired number of air inlet holes 10 which are controlled bya slide ring 11 having a grasping handle of any desired construction.

An upper cored or a r jack t fir p t I 12 has a water chamber 18 the lower portion .of which is connected by conduit 14.- with the upper portion of thewater chamber 5 of theiprehea'ter. Y i

The lower water, jacket? is provided with a hot water discharge pipe 15, and the upper fire pot 12 is previded with a hot water discharge pipe 16. The lower fire potis provided with an inlet pipe 17. The top 18 is supported on the upper fire pot and has a removable lid 19 covering the opening through which the fuel is introduced into the stove. The top 18 has a chamber leading to the damper controlled exitfiue 20.

h o om g ate 2. i a ny d r d r on nt o al t str ctio is supp ted Q1} a rate rest 22, and hasan extension 23 whlch is aperturedto receive a shaking bar or lever of the usual construction. 24 designates a support for the upper grate 25. The sup port 24: as illustrated consists of a base 26 consisting of sides 27 having depending lugs 28, the sides being connected by a cross bar 29 having an opening to receive a bar 30 which is fixed inposition by means of a fastening device 31.- A bar 32 is adjustably connected with the bar 30 by means of fastening' devices 33 which pass through register-c ing apertures 3 1 in the two bars.

In the position shown in Figures 1 and I, the upper grate is in what may be called its neutral position, that is, it will only heat the upper fire pot. If the bar 32 is lowered one hole, there will be a one inch fire contact with the upper portion of the wall of the lower fire pot. I provide a plurality of adjustable positions for the upper grate and have indicated in Figure 4- on the bar30 the positions of adjustment for a one, two, three or four inch fire contact with the lower fire pot 7.

The bar 32 has pivoted to it at its upper end, as at 35, a stud'36 having a polygonal contour at its upper end to adapt it to enter a polygonally shaped recess 37 in the upper grate 25. The bar 32 has fixed to it one end ofa spring 38 the'free end of whichbears against the stud 36 to retain the upper grate 25 in a horizontal position. j

The operation of my novel stove is as follows I In the winter time a fire is built on the lower grate 21 and the lower fire serves as a source of heat for the lower fire pot and also the preheater 4; and the upper fire pot 12 with which it communicates.

The upper fire pot 12 and the preheater 4 form the hot water supply for household purposes, such as the hot water supply for the bath-room and for the kitchen. The fire pot 7 forms a source of hot water supply for the radiators, so that two independent hot water heaters are provided in the same stove. In the summer when the radiators are not in use, the support'24 is inserted in place so that the lugs 28 extend between the grate bars of i the lower grate 21, and the bars 30 and 32 are relatively adjusted, so that the upper grate 25 is positioned so that it will onlyheat the upper fire pot 21.

In the spring and fall, when it is desired to have a little heat in the radiators but not enough to make it necessary to. build 'a fire on the lower grate, the bars-3O and 32 are adjusted so as to lower the upper grate into such position that the fire on the upper grate will have a direct fire contact with the upper Wall of the lower fire pot 7 For example, when the parts are adjusted for a the zero aperture, the lower grate is in its neutral position so that it will only heat the upper fire pot 12. I have illustrated four adjustments so that by lowering the bar 32 either a one, two, three or four inch fire contact can be obtained with the walls of the fire pot 7 and still a suflicient hot water supply will be obtained from the fire pot 12 for household purposes, such as, for example, the kitchen and the bath. 7 V I When it is desired to dump the upper grate 25, the cover 19 is removed, and a poker is inserted to rock the grate 25, so that the ashes and fire will drop to the lower grate.

It will be apparent that the upper fire has an independent source of draft, controlled by the slide ring 11'; or when lowered below this ring, the usual draft forthe lower grate 21 is employed to provide'the draft for primary combustion. When it is desired to shake the upper grate all that it is necessary to do'is to shake: the lower grate 21 by the handle 23, V

and, since the support is interlocked with ithe lower grate, the upper gratewillbe mov'edin unison therewith.

My present inventionhas been found in pract ce to give advantageous and reliable 7 results, since a multiple heating system is provided wherein an unskilled person can relatively adjust the support.24:so that the upper fire can have a desired 'fire contact with the walls of the lowerfire pot, so that whenever desired, the radiator hot water system as well as the household system for 1lgiot water can be heated from, the same upper v Having thus described invention, what I claim, as new and desireto secure by Let-- ters Patent, is r a '1. In a stove, superimposed fire pots each per fire openingthrough-the side walls of the stove between said fire pots, and means to adjust the location of said upper fire to cause it to have a desired fire contact with the lower of said fire pots 1 2.
